Description

  The present invention relates to a protector mounting method to a wire harness and a protector mounting structure to a wire harness, and in particular, prevents biting between a protector main body and a lid of a wire harness inserted through the protector.

In many cases, a protector made of a resin molded product is attached to a wire harness routed in a vehicle for the purpose of protecting a group of wires from external interference with other in-vehicle devices and regulating a wiring path.
In particular, in recent years, the number of equipment installed in the engine room of vehicles has increased, and from the standpoint of collision safety, the harness wiring space has been required to be reduced. Is getting complicated. For this reason, the number of protectors used to realize this complicated path regulation is increasing in the number of complicated shapes having the bent portion 2 as in the protector 1 shown in FIG.

  When wiring an electric wire directly to this kind of protector, when there is a wire hook or when there is a large amount of wire in the wire harness, it is not easy to keep the electric wire from protruding from the protector. In particular, when the bent portion 2 is provided like the protector 1, as shown in FIG. 23 (B), the wire w is routed through the bent portion 2 even if the wire w is inserted into the hook-shaped wire inserting portion 3. It is difficult to follow the cable, and it takes time and effort to return the protruding wire. In addition, when closing the lid 5 connected to the wire insertion portion 3 via the hinge 4, it is easy to bite the electric wire w overflowing on the open / close end 5a side of the lid 5, and the hinge 4 is not provided. In the bending part 2, it becomes easy to bite the electric wire w on the recessed part 2a side of the bending part 2. Therefore, there are problems in that man-hours increase in order to eliminate biting, and line trauma due to biting tends to occur.

  Various structures have been proposed for preventing the electric wire from protruding from the protector and the electric wire from being covered by the lid. For example, in Japanese Patent Application Laid-Open No. 7-245839 (Patent Document 1), the applicant of the present invention, as shown in FIG. A lid 6b is provided, and an electric wire locking plate portion 6d protruding from the upper end of the side wall 6c of the electric wire insertion portion 6a is projected from the upper surface opening of the electric wire insertion portion 6a, and the base end portion of the electric wire locking plate portion 6d A protector 6 is proposed in which a slit 6e is cut from the upper end in a side wall 6c continuously on both sides.

  In the protector 6, when the electric wire is inserted into the electric wire insertion portion 6a, the electric wire locking plate portion 6d is displaced outwardly to allow the electric wire to be inserted. The electric wire displaced in the direction and accommodated in the electric wire insertion portion 6a can be pressed from above to prevent the electric wire from being lifted or protruding, and to be prevented from being caught when the lid 6b is closed.

  However, a protector provided with this type of wire protrusion prevention structure has a problem in that the structure becomes complicated and the cost of the mold becomes high and the cost is high. Moreover, although a small protector may be used for reasons such as a small wiring space, it is difficult to provide the structure for a small protector.

JP-A-7-245839

  The present invention has been made in view of the above problems, and prevents the protrusion of the electric wire and the electric wire between the protector main body and the lid without providing a special structure to the protector, thereby reducing the man-hour and the cost. It is an issue.

In order to solve the above-mentioned problem, the present invention is a method for attaching a protector to a wire harness routed in a vehicle,
While the protector holding jig installed on the wire harness assembly work table is erected on the distal end side with a wire regulating rod provided with a wire pressing part that is displaced in an upright posture and a bent posture,
The protector is formed of a resin molded product having a main body composed of a bottom wall and both side walls, and an open / close lid connected to one side wall of the main body via a thin hinge portion, and the bottom wall is provided on the side wall. In addition to providing a first through hole that allows the wire holding portion to pass through in an upright position at a position along, a second through hole that allows the wire holding portion to pass through the lid in a bent posture is provided.
When the protector is placed on the protector holding jig, the wire holding portion of the wire regulating rod is passed through the first through hole as an upright posture, and the wire holding portion is displaced in a bending posture inside the protector body. Let
Next, the wire group constituting the wire harness is inserted into the body of the protector, and when the wire is inserted, the wire holding portion suppresses the lifting of the wire,
When closing the lid of the protector, close the wire holding portion in the bent posture while passing through the second through hole,
Provided as a first attachment method is a protector attachment method to a wire harness in which the closed lid is locked to the side wall of the main body and then the protector is pulled out from a protector holding jig with the wire holding portion in an upright posture. ing.

  According to the first attachment method of the present invention, the wire group inserted into the body of the protector is suppressed from being lifted or protruded by the wire pressing portion of the wire control rod penetrating the protector, and the wire control By closing the lid while holding the electric wire with the rod, it is possible to prevent the electric wire from being caught between the body of the protector and the lid. Therefore, the protector itself does not need to be provided with a wire lifting prevention portion or a biting prevention portion, and simply by providing the first through hole and the second through hole through which the wire regulating rod passes, the wire can be easily and reliably provided. Can be prevented from lifting and biting.

  Therefore, the mounting method of the present invention does not need to tape the wire group before inserting it into the protector or inserting the wire protruding from the protector, and can reduce the man-hours for wiring the wire to the protector. Since it is not necessary to provide the protector itself with a complicated structure, the manufacturing cost can be reduced, and application to a small protector is also possible.

It is preferable that the wire regulating rod protruding from the protector holding jig is disposed at least on the opening / closing end side of the lid facing the thin hinge portion of the protector.
Thereby, when locking the open / close end of the lid to the protector body, it is possible to reliably prevent the electric wire from protruding and being caught when the lid is closed.

In the case where the protector includes a bent portion, and there is no connecting portion formed of the thin hinge portion between the lid and the main body at the bent portion, and is divided by the lid, the main body, and the bent portion, the wire regulating rod Are arranged on the attachment side of the lid at the dividing position.
This prevents the electric wire from protruding from the lid mounting side of the bent portion where the electric wire is particularly likely to protrude due to the absence of the connecting portion between the lid and the main body. It can be effectively prevented.

  The electric wire restriction rod has a U shape having restriction rod portions on both sides, the wire holding portion is provided at the tip side of the restriction rod portions on both sides, and the inside of the protector main body is in a bent posture. The wire group to be inserted may be prevented from rising from both sides.

  Thus, by setting it as the structure which suppresses the raising of an electric wire group from both sides, the protrusion from the protector main body of an electric wire can be prevented more reliably. In particular, the bent portion where the electric wire may protrude from both the attachment end side and the open / close end side of the lid is effective because the electric wire can be prevented from protruding and biting on both sides.

The wire regulating rod is made of an elastic member, and the wire holding portion on the distal end side is shaped in advance in a bending posture, and can be displaced by elastic deformation from the bending posture to an upright posture.
Alternatively, the electric wire regulating rod is formed of a rigid body, and the electric wire pressing portion on the distal end side is connected to the upright posture and the bent posture via a pin so as to be displaceable.

  Further, the present invention provides a wire harness in which the protector is attached to the wire harness by any one of the methods described above, the first through hole is provided in the body of the protector, and the large through hole is provided in the lid. A protector mounting structure is also provided.

Furthermore, the present invention provides a second method of attaching the protector to the wire harness routed in the vehicle.
A protector holding jig is erected on the wire harness assembling work table, and an inverted L-shaped wire regulating rod provided with a wire pressing portion bent in the horizontal direction at the tip side is connected to and separated from the protector holding jig. While slidably installed in the
The protector is formed of a resin molded product having a main body composed of a bottom wall and both side walls, and an opening / closing lid connected from one side wall of the main body via a thin hinge portion, and on the upper end side of the side wall, There is a through hole in the wire holding part of the wire restriction rod,
Place the protector on the protector holding jig, let the wire holding part of the wire regulating rod penetrate the through hole, and protrude inside the body of the protector,
Next, the wire group constituting the wire harness is inserted into the body of the protector, and when the wire is inserted, the wire holding part suppresses the lifting of the wire,
After the lid of the protector is closed and locked to the main body, the wire restraining rod is slid to remove the wire holding part from the protector, and the protector is removed from the protector holding jig. It is provided as a second mounting method.

Also in this second mounting method, as in the first mounting method, until the lid is closed by inserting the electric wire through the protector body, the electric wire is pressed by the electric wire holding portion of the electric wire regulating rod, and the electric wire Since the protrusion and the biting can be prevented, the workability of wiring the electric wire to the protector can be improved.
In addition, the protector only needs to be provided with a through hole that penetrates the wire holding part of the wire regulating rod, and there is no need to provide any other complicated lifting prevention structure or anti-jaw structure. The manufacturing cost can be reduced.

It is preferable that the wire pressing portion of the wire regulating rod protrudes into the main body of the protector at least on the opening / closing end side of the lid facing the thin hinge portion of the protector.
Thereby, it can prevent effectively that an electric wire protrudes from the opening-and-closing end side of the main body of a protector, and is caught when the lid is closed.

  By forming the wire pressing portion with an elastic member in this way, the lid can be closed with a light force even when the wire pressing portion is penetrated, and the burden on the operator is reduced. In addition, since the wire pressing portion bends inward as the lid is closed, the force for storing the wire in the protector main body is increased, and the protruding or floating of the wire can be prevented more reliably.

  Further, the present invention provides a protector mounting structure for a wire harness in which a protector is attached to a wire harness and the through hole is provided in a body of the protector by any one of the second attaching methods. providing.

  As described above, according to the present invention, the wire restriction rod provided on the protector holding jig is inserted into the protector main body from the outside, and the electric wire in the protector main body is pressed by the electric wire holding portion of the electric wire restriction rod. The lid can be closed while pressing down. Accordingly, the work of returning the electric wire protruding from the protector main body and the work of tape winding the electric wire can be omitted, the workability of attaching the protector to the wire harness can be improved, and the electric wire is caught when the lid is closed. Line trauma can also be prevented.

  In addition, it is not necessary to provide a complicated wire lifting prevention structure or biting prevention structure in the protector body, and it is only necessary to provide a through hole for inserting the wire restriction rod from the outside. And cost reduction and application to a small protector.
